10 weirdest Things Evolution Left In Your Body

1-coccyx (TAIL BONE)

Before you were born,you had a tail albeit only for few weeks.All mammals develop a tail as ambryos in the womb,but human lose it again before birth (except in a few very rare cases).The COCCYX,or tail bone at the bottom of ur spine is this tail’s last remnant.

2-Third Eyelid

In the corner of your eye,next to the tear duct is the remnant of a third eyelid technically known as the PLICA SEMILUNARIS.In many reptiles and birds and some mammals,this translucent ‘nictitating'(blinking)membrane can be drawn horizontally across the eye for moisturisation ,extra protection or to remove debris.In humans,it plays more minor roles such as assisting tear drainage .

3-Wisdom Teeth

Most people only become aware of their wisdom teeth thanks to theethaches in their late teens and early twenties.These extra molars were probably used by our larger-jawed ancestors to grind up raw plant material.Now,these teeth are virtually useless and their removal is one of the most common surgical procedures.

4-Darwin’s point

Around a quarter of the population has a small bump on the upper edge of the ear,known as Darwin Point after its description in Darwin’s THE DESCENT OF THE MAN .The position of the bump matches of the location of more prominent points in the ears of many of our primate cousins ,providing another sign of our common ancestry.

5-Palmaris Longus

Around 85% of people have a palmaris longus a vestigial muscle running from the elbow to the heel of the hand.In some primates this muscle assists climbing,while in cat and other predators ,it retracts the claws .You can test if you have it by flexing your wrist and touching your fifth finger to your thumb -if it’s there ,it will pop up .

6-Jacobson’s Organ

Also called the vomeronasal organ ,this is an important smell sensor in many animals ,from elephants to salamanders.Some studies suggest humans have a remnant of this organ at the back of the nose ,but as there are on nerves connecting it to the brain ,it is unlikely to play a role in sense of smell .

7-Goosebumps

Goosebumps appear when you are frightened ,or a bit chilly thanks to tiny muscles called arrector pili surrounding hair follicles in your skin; when these muscles connect your hairs stand up . In humans such hair raising has little effect but it could have made our furrie ancestors appear large when threatened and would have provided insulation in cold weather by trapping a layer of air by the skin .

8-Plantaris Muscle

The plantaris is small muscle that plays such a minor role in humans that around 10% of the population does not have it at all.Situation behind the knee this muscle connects to the ankle via a long tendon that in our more flexible primate relatives can be used to make the foot grasp branches or pick objects.

9-Auriculares muscles

If you have ever seen someone wiggle their ears then you have seen them use a set of vestigial muscles called the auriculares muscles.Cats dogs and many other mammals use these muscles to move their hearing .Our ancestors all but lost this ability making the muscles good for little more than the occasional party trick.

10-Palmar Grasp Reflex

Place an object in the hand of a baby under five months old and the fingers will automatically close around it with a surprisingly strong grip. This reaction known as the palmar grasp reflex is a throwback to hairier times when babies of our predecessors would have clung to their mothers by gripping their body fur.
